Aurora

AURORA shows
how reflections are created both by the shape of the light and the
shape of the reflector. The reflector is a large curved sheet of
brushed stainless steel. The tiny ridges in the steel act like tiny
mirrors, each reflecting an image. When the images from all the
ridges add up, they blend into a single elongated image that looks
like a ribbon of light. The many colored tiles with the exhibit
let you experiment with both the shape and color of the reflections.
